A typical urban and suburban environment has numerous sources contributing to the exterior ambient noise. Among these are the environmental sounds from a building’s heating, ventilating, and air-conditioning equipment. How can design professionals help mitigate the distraction caused by HVAC?
As consulting engineers continually specify more sustainable HVAC technologies, they must ensure their designs comply with a variety of standards. Of course, when possible, it is even better to go far beyond those baseline requirements. In this respect, the University of Findlay’s $11 million Davis Building is a role model for future commercial mechanical technology.
When Texas State Bank (TSB) opened its headquarters in San Angelo, in 1977, the HVAC on its rooftop was a state-of-the-art chilled water loop system. Three decades later, and annual cooling tower costs were spiraling. Outfitting the four-story building with an energy-efficient variable refrigerant flow (VRF) system provided a desirable solution.
Until now, design professionals have had to rely on adding off-the-shelf actuators to standard windows to provide automated natural ventilation in a building. With this as the only available solution, there have been several problems.
